Users should be able to restrict what models are used in automations. I thought it was only going to use the BYOK model I selected, but it launched subagents with Copilot models and used all my credits.

从 /chat 路径开始，跟踪自动化如何选择模型并启动 subagents。定义用户允许的模型限制应如何应用于自动化 subagents，然后验证未获批准的 Copilot 模型不会被使用，并且所选的 BYOK 模型仍在该限制范围内。
